Check the following:
•
Determine if the interrupt (IRQ) setting assigned to the Ethernet
controller is also assigned to another device in the
Configuration/Setup Utility program.

Although interrupt sharing is allowed for PCI devices, some
devices do not function well when they share an interrupt with
a dissimilar PCI device. Try changing the IRQ assigned to the
Ethernet controller or the other device. For example, for
NetWare Versions 3 and 4 it is recommended that disk
controllers not share interrupts with LAN controllers.
